olfactory

These lightning-fast olfactory capabilities are not interesting merely as biological trivia.

Migratory locusts differ from other insects in the anatomical structure of their olfactory brain, the antennal lobe, which receives and processes olfactory information from the antenna.

Scientists have pondered how insects are able to smell, or extract information from odors, with a much smaller olfactory sensory system compared with mammals.

Odors play an important role in guiding motivated behaviors such as food intake, and -- in turn -- olfactory perception is modulated by how hungry we are.

"But compared to research on the benefits of seeing nature, we don't know nearly as much about how the impacts of nature's scents and olfactory cues affect us."
